When assessing a client with a serum potassium level of 7.5 mEq/L (7.5 mmol/L), which intervention is most important for the nurse to implement?

Choice A reason: This is the most important instruction because lowering the bed reduces the risk of injury to both the client and the UAP. It also makes it easier for the UAP to use proper body mechanics and leverage when assisting the client to move up in bed.

Choice B reason: This is not the most important instruction because encouraging the client to eat all of the meals that are sent is not directly related to repositioning the client. While adequate nutrition is important for wound healing and recovery, the nurse should assess the client's appetite, dietary needs, and preferences before instructing the UAP to encourage the client to eat.

Choice C reason: This is also not the most important instruction because offering fruit juice at least twice during both the day and evening shifts is not directly related to repositioning the client. While adequate hydration is important for preventing constipation and promoting circulation, the nurse should consider the client's fluid status, blood sugar levels, and potential interactions with medications before instructing the UAP to offer fruit juice.

Choice D reason: This is another incorrect instruction because having the client hold a pillow over the abdomen to cough and deep breathe is not directly related to repositioning the client. While coughing and deep breathing are important for preventing respiratory complications and promoting oxygenation, the nurse should instruct the client to perform these exercises at regular intervals, not only when repositioning.

Choice A reason: This is not the best intervention as it does not address the cause of the pain or provide adequate relief. Deep breathing may help the client to relax and cope with the pain, but it is not enough to manage severe pain.

Choice B reason: This is not a true or helpful statement as it may imply that the nurse is dismissing the client's pain or delaying further action. Oxycodone is a fast-acting opioid analgesic that reaches its peak effect within 30 to 60 minutes. If the client is still in severe pain after one hour, the nurse should reassess the pain and notify the healthcare provider.

Choice C reason: This is not the priority intervention as it does not address the cause of the pain or provide adequate relief. A backrub may help the client to relax and distract from the pain, but it is not enough to manage severe pain.

Choice D reason: This is the best intervention as it helps the nurse to evaluate the effectiveness of the medication and the need for further intervention. The nurse should use a valid and reliable pain assessment tool and ask the client about the location, intensity, quality, and duration of the pain. The nurse should also check the client's vital signs and observe for any signs of adverse effects from the medication.
